Charlton Athletic have named and shamed Portsmouth in front of their Premiership peers for attempting to poach the Addicks' £1.5m-a-year title sponsor.

Charlton's commercial director Steve Sutherland sent an email last Monday to his counterparts at every top-flight club to expose the machinations of Alan Kimber, Pompey's sponsorship and advertising manager. Kimber had contacted Llanera, a Spanish property company with a £6.6m deal to sponsor Charlton's shirts until at least 2010, offering "an opportunity to maintain marketing exposure in the Premiership next season in the event of Charlton being relegated".

But in an unfortunate twist for Kimber, the email was sent to Llanera UK's managing director, Emilio Teresa, while he was in Spain with Charlton's chief executive, Peter Varney.

Teresa immediately tipped Varney off and it was decided that the Premiership should be warned about Pompey's tactics. Kimber, who Portsmouth say is currently on holiday, also mentioned that his club pride themselves in "not targeting some of the down-market brands traditionally associated with football".

Sutherland could not believe what he was reading. In an email entitled "Interesting Approach!", he wrote: "Why waste time putting in the effort to research the sponsorship market and make time-wasting presentations to potential partners when you can simply contact someone else's partner, preferably a club fighting relegation and get them to move across? Brilliant."

Gambling rules overhaul

The Gambling Commission will today issue its consultation document aimed at overcoming data-protection issues surrounding information sharing between bookmakers and sports' governing bodies. The commission currently has an arrangement entitled "condition 15", which provides for sports regulators to receive notification of bookmakers' concerns over irregular betting patterns. However, it will seek to expand the scope of condition 15 with its possible introduction as a mandatory licence condition in time for implementation in September. There are fears that the move will drive bookmakers or their business overseas, although one aim of the consultation is to encourage bookies to remain UK-based. Whatever the outcome, however, the four football managers whose Victor Chandler accounts are the subject of an injunction preventing their publication by a former employee are safe. As an offshore company based in Gibraltar, Victor Chandler is not regulated under the Gambling Act.

Nike faces 'gazump' claim

Nike's gazumping of Adidas as kit supplier to the Germany football team has led to the European sportswear giant taking the German football federation (DFB) to arbitration. Adidas says it and the DFB issued a statement last August announcing the renewal of an association stretching back to 1950. That was understood to value the deal at £7.5m a year between 2011 and 2014 but six weeks after the statement Nike announced an eight-year deal said to be worth £340m. Adidas is seeking to hold the DFB to its verbal agreement, although it may offer an enhanced deal.

Tesco deal

The Football Association's development partnership agreement with Tesco, announced yesterday, will produce £1m worth of direct investment in women's football, aimed ultimately at fostering a fully professional women's league.

Olympics under scrutiny

Ken Livingstone faces an Olympic grilling tomorrow from councillors at the London Assembly's City Hall during mayor's question time. Amid fears host cities are crippled by debts for decades, Bob Blackman, a Conservative councillor in Brent, will demand that the 38p-a-week Olympic precept - a levy on council tax - must not be extended beyond 12 years. The Green party's former deputy mayor, Jenny Jones, is laudably asking that all eggs used in Olympic catering are free range.
